It became an issue because of a recent change in doprnt.c, and because
the NS port is the only one that uses non-ASCII characters in that
format string.

I'd prefer to lift the restriction introduced by doprnt.c, instead of
replacing that character.  It isn't clear to me why this restriction
is a good idea, and it doesn't seem like lifting the restriction
should be hard.  Patches welcome.
